Generic Viagra

When choosing a drug for ED treatment you also take into account its price. It’s when you decide what to choose — a Generic Viagra or a branded one.

Viagra created by Pfizer, Inc. was the first medication to fight against erectile dysfunction. Its active substance Sildenafil was designed to cure some heart diseases. But it was its side effect of enhancing erection that made Viagra the most effective and the most popular ED medication all over the world.

The company obtained a patent for both the active substance Sildenafil and its brand name Viagra.

Eventually the patent license on a drug runs out (this period is usually 15-20 years) and the Medicine and Healthcare products Regulatory Agency (or MHRA) allows other companies to produce the same drug.

In this case they cannot use its original brand name. These companies only sell drugs based on the same active ingredient but under the name of its active ingredient Sildenafil. It explains why there is a range of the similar medications with the same active substance but with different names. The main difference between these drugs and the branded Viagra is the price which is much lower in the case of generics.

Both Viagra and its different generics are produced in 25mg, 50mg, and 100mg preparations, and have almost the same chemical structure. Generic versions of a drug are required to contain the same active substance as their branded alternative so they have the same effect and pharmaceutical characteristics.

According to the FDA, generic medications have the same mode of action and assure identical benefits as branded versions. Before being approved by the FDA all the generics are carefully studied and have to meet all the legal requirements.

The main asset of generic medications is their low price comparing to the branded one.. According to the FDA, market competition makes prices for generic drugs lower than those of branded ones up to 85% lower.

Sildenafil (C28H38N6O11S), the active substance of both branded Viagra and its generic, belongs to the group of inhibitors of type 5 phosphodiesterases (PDE5) that influences smooth muscle of penis and enhance blood flow in order to achieve productive erection.  

It is necessary to notice that generic and brand-name Viagra may have some differences in formal features. The color, shape, packaging, and labeling of the medicine may vary. Branded Viagra in produced in the form of small diamond-shaped blue pills as Pfizer has also patented the design and appearance of this pill. Generic Viagra has the form of white or blue pill, with different characteristics depending on the brand. Inactive ingredients of generic drugs may also change their flavoring but actually have no effect on the supposed effect of the medication.

Drugs with Sildenafil are only available on prescription. Medical consultation is also needed in order to check whether you are allowed to take Viagra according to your health situation and to establish the best efficient dose for you. Never start taking or change your dose of Viagra without consulting your healthcare provider.

Sildenafil remains in the blood during 4-6 hours. It is desirable to avoid alcohol during this period in order not to overload your organism. Such combination is dangerous for your health. You also need special medical consultation before taking Viagra if you suffer from heart, kidneys or liver diseases.

As Viagra and its generic have the same chemical structure, they have a lot in common.

Both medications have the same dosage to be prescribed. They also imply keeping to the same precautions and may provoke similar side effects.

These effects are usually mild and disappear after several hours or after a couple of takings.

The most common side effects of Viagra are a headache, nausea, facial flushing and hot flushes. Cases of indigestion, nasal congestion and dizziness after taking Viagra have been also reported. All of them are temporary but you should avoid driving or operating machinery if you experience these side effects for security reasons.

Viagra may also provoke a visual disturbance, such as blurred vision or problems of distinguishing blue or green. It usually disappears after a few minutes. If this state is prolonged or provokes serious troubles with vision you should seek medical aid immediately.

In rare cases side effects can become more severe including redness, pain or sensitivity, a rapid heart rate, hypo- or hypertension, back pain, stomach problems, muscle aches, nasal congestion, rashes, irregular heartbeat, stroke or a heart attack, hearing difficulties. 

Be careful when it comes to priapism (a persistent painful erection of more than 4 hours). If you experience such a condition, you should seek medical aid immediately to avoid long-term damage to your body.

Viagra cannot be combined with a range of medications. You cannot take Viagra with other ED medications, bosentan, cimetidine, conivaptan, imatinib, isoniazid, antidepressants, antibiotics, antifungals, drugs to treat high blood pressure or a prostate disorder, heart or blood pressure medications, hepatitis C medications, or HIV/AIDS medicines. Inform your doctor about all the medications you are currently using before starting taking Viagra to assure safe and efficient treatment.
